[Q] How do I install clockworkmode recovery on lg p930 v20c stock ICS ROM

Hi guys,
I have a rooted LG Nitro HD running stock ICS and v20c firmware, I will like to install clockworkmod recovery to flash a custom ROM. The last time I installed CWM, it couldn't enter recovery mode giving me a "boot secure error". I was able to overcome that to boot into stock recovery but I need CWM to install a custom ROM. Any help guys?
Phone is LG p930 nitro HD, v20c firmware and stock ICS 4.0.4.

havnt seen unbricking guide that closly but yes....
just flash the stock 2.3 kdz using kdz flaher and than from recovery wipe that will fix any reboot issues.
now root and put cwm.

please post guide to flash f180k with european e975

i have a rooted f180k.i already unlocked the bootloader with freegee, however i cannot find any compatible custom recovery,eg cwm. how can i install e975 european rom on my phone? please explain im new to android
lol, enter the download mode -> flash E975.kdz -> Profit
You dont need root, custom recovery or unlocked bootloader for this.
FreeGee installs a recovery.
why you would Flash a KDZ which is not for your Phone?
flashing e975 kdz to f180l is possible but be reminded that your network signal may become problematic like my phone, im still stuck with ics 4.0.4 because whenever i update to f180l 4.1.2 via ota my network signal is lost, already tried flashing e975 rom and f180l baseband but to no avail..

[Q] LG G3 - Recovery boot problem

Hi guys,
I rooted my lollipop running G3.
When I tried to install recovery, it says that it was installed succesfully, but when I want boot into the recovery,
phone stay in black screen with "Secure Booting Error! Cause: boot certification verify".
I have tried most methods to install it,,,flashify, window commands and so on ...
Is there any solution to get recovery on my G3 without downgrade to kitkat? ...
(sorry for my bad English)
Thank you, best regards.
No. Only way is to downgrade to kitkat. There is no recovery available for Lollipop at the moment although there is root, and there is a thread on here somewhere that shows how to get recovery on Lollipop by extracting the aboot file, but it is way too complicated for me.

Error when trying to flash cm 12.1

Hi there! I've just tried to flash the latest nightlie to my device (LG Optimus G E-975) and got this error (Screenshot). Any idea how could I fix it? Thanks for your help
PS: I'm using the latest version of TWRP (Official) you could see that in the screenshot.
the second one here is the latest https://mirrors.c0urier.net/?dir=android/Dadi11/Required files/Recovery
also flash this https://mirrors.c0urier.net/?dir=android/Dadi11/Required files/Bootloader Update
Hi! Thanks for the revovery and bootloader, I flashed both of them, but still got the same error when trying to flash the ROM. I think it has something to do with the device's name "This package is for device: e975; this device is geehrc4g." Do you know how to fix that?
